Urinary Tract Infection
Overview Infection of the urinary tract is common and more so in women (due to shorter urethra and hormonal changes). UTIs may be classified as either a lower (Cystitis, urethritis and Prostatitis) or upper UTI (pyelonephritis). The main causative agents are bacteria such as E-coli. A lower UTI can progress to an upper UTI causing systemic symptoms…

Hyperemesis Gravidarum
Overview Hyperemesis gravidarum (HG) exists on a spectrum of nausea and vomiting in pregnancy (NVP). NVP refers to symptoms of nausea, vomiting or dry retching commencing in the first trimester, with no other cause identified. 1 HG refers to severe, persistent vomiting that may result in malnutrition, dehydration, weight loss and debility due to illness.…

Enteropathic Arthritis
Overview Enteropathic arthritis is a subtype of spondyloarthropathy associated with inflammatory bowel disease (IBD), particularly Crohn’s disease and ulcerative colitis. It affects up to 20% of IBD patients, with a variable presentation involving axial and/or peripheral joints. The arthritis may run parallel to intestinal disease activity or occur independently, often with enthesitis or dactylitis. It…

Chronic Pancreatitis
Overview Chronic pancreatitis is a progressive fibro-inflammatory disease of the pancreas that causes irreversible structural damage and eventual loss of exocrine and endocrine pancreatic function. It commonly presents with recurrent or persistent upper abdominal pain and may later cause malabsorption, weight loss and pancreatogenic diabetes. Alcohol exposure and smoking are important causes and accelerators, but…

Community Acquired Pneumonia
Overview Community acquired pneumonia occur in individuals who are not in hospital (or have been in hospital in the past 48 hours) and who are not significantly immunocompromised. The World Health Organization estimates that lower respiratory tract infection is the most common infectious cause of death in the world. Choice of antibiotics are usually empirical…

Chronic Exertional Compartment Syndrome (Exercise-induced Compartment Syndrome)
Overview Chronic compartment syndrome (also known as chronic exertional compartment syndrome or exercise induced compartment syndrome) is an exertional condition in which repetitive activity causes transiently elevated pressure within a closed myofascial compartment, leading to ischemic pain, tightness, and sometimes neurologic symptoms that predictably begin with exercise and abate with rest. It most often affects…

Benign Prostatic Hyperplasia
Overview Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate gland. There is an increase in stromal and glandular components. Anatomy The prostate is an male organ that sits inferior to the bladder and surrounds the first part of the urethra. It is oval shaped and approximately 4cm thick. The prostate gland is…

Good places to begin
Explanations learners return to.
COPD – Investigations and Treatment (PART II)
Learn about the key investigations used to diagnose Chronic Obstructive Pulmonary Disease (COPD), including spirometry and imaging techniques. This video also explores evidence-based treatment options such as bronchodilators, corticosteroids, oxygen therapy, and lifestyle modifications.
Coagulation Cascade and Fibrinolysis – clotting factors, regulation and control mechanism
Explore the coagulation cascade and fibrinolysis, detailing the roles of clotting factors and the step-by-step process of blood clot formation. This video also explains how these pathways are regulated and balanced by control mechanisms to prevent excessive bleeding or clotting.
Coeliac (Celiac) Disease – Overview (signs and symptoms, pathophysiology, diagnosis, treatment)
Learn about coeliac disease, an autoimmune condition triggered by gluten that damages the small intestine. This video covers its signs and symptoms, underlying pathophysiology, diagnostic approach, and effective treatment strategies including a gluten-free diet.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Aortic Aneurysm
Overview An aortic aneurysm is a pathological dilatation of the aorta caused by weakening of the arterial wall. It may involve the aortic root, ascending aorta, arch, descending thoracic aorta, thoracoabdominal aorta or abdominal aorta. Most aortic aneurysms are asymptomatic and are discovered incidentally or through screening. Progressive enlargement increases the risk of rupture, dissection,…
